I seem to recall a snippet of dialogue talking about the timeline wanting to repair itself...did I imagine it?

It was apparently discarded material intended by the writers as one way of looking at the situation with the seeming coincidences/contrivances in the film.

Figuring out ways to get the crew together required some contrivances, which Orci and Kurtzman wanted to explain from old Spock as a way of the timeline mending itself, highlighting the theme of destiny. The line was very difficult to write and was ultimately cut out.
